Progressive Suspension has focused exclusively on American V-twin suspension since 1982, and its Monotube fork cartridges and 400/970/970G shock series are among the most common upgrades on baggers and Softails. For most riders the stock rear shock is the single worst part on the bike — this is the fix.
Transform your Harley-Davidson M8 Softail's ride with the Progressive 465 Series R.A.P. remote adjustable preload shocks. These high-performance monotube shocks feature a 46mm bore with deflective disc damping and hand-tuned valving, delivering exceptional control and comfort. The integrated R.A.P. system allows for quick, tool-free preload adjustments, making it easy to dial in your suspension.
The Progressive 465 Series R.A.P. shocks are engineered for riders who demand both performance and convenience. The remote adjustable preload (R.A.P.) system, with its hand-adjustment knob, lets you quickly adapt to changes in load or riding style. Coupled with a 5-position rotatable rebound damping adjuster, you have precise control over your Softail's suspension characteristics, ensuring an optimized ride every time.
These shocks are offered in multiple lengths, allowing you to fine-tune your M8 Softail's ride height and achieve your desired stance. Whether you're setting up for aggressive canyon carving or comfortable touring, the combination of hand-tuned valving and R.A.P. technology provides a versatile and high-performing suspension solution. Pair these with a complementary front-end upgrade for a fully balanced and superior handling package.

The shocks seem super nice, but they are incredibly stiff. Turns out they’re 130/200 top to bottom. Would be nice to have an option to choose your spring rate. Couldn’t find it in the description either. Have them installed on a 1998 sportster 1200 by the way. I’m about 180lbs and they don’t move at all, my friend who weighs about 260 also said they were way to firm. Hope this helps.
